oI-L BURNER Application filed November 13,-1.923. Serial no. 674,576.

To all whom it may ooncewt:

Be it known that I, OLUF Annnnsnn, a citizen of the United States, and a resident of'Los l-hngelesin the county of Los'Angeles,-and-State of -California.;have invented certain new and useful Improvements in Oil Burners, of'which the following is a burner body to permit rapid Va-POI'lZZLUOII of the fuel and to facilitatetheapplication and removal of the pipe to and from the burner.

body.

I will describe only one form of oil burner embodying my invention and will then point out the novel features thereof in claim.

In the accompanying drawings Figure 1 is a view showing in side elevation, and partly in section, one form of oil burner embodying my invention;

Figure 2 is a vertical sectional view taken on the line 22 of Figure 1;

Figure 3 is a fragmentary sectional view taken substantially on the line 33 of Figure 2;

Figure 4 is a top plan view of the burner shown in Figure 1.

Referring specificially to the drawings, in which similar reference characters refer to similar parts, my invention in its present embodiment comprises a burner body 15 made from a single casting and preferably, although not necessarily, of rectangular form, to provide a vaporizing chamber 16 to which oil is supplied from a suitable source (not shown) by a pipe 17 provided with a valve 18. As clearly shown in Figure 2, the pipe 17 is threadedly fitted in an opening 19 formed in one side of the burner body 15, so as to communicate with the chamber 16 at the bottom thereof. The top of the burner body is provided with a tray or pan 20 recessed as indicated at 21, and

this tray is, as clearly shown in Figure, of an area exceeding that of the burner body, although being integrally formed therewith.

The side walls of the burner body 15 are formed with openings 22, and as clear ly shown in Figure 3 these openings are reverseiy threaded to receive the reversely threaded ends 2347f a burner pipe 2st. The

burner'pipe 24 is of substantially C-shaped form, and in applled position upon the burner body its intermedlate portion, designated at 249. is disposed above and along the longitudinal axis of the pan or tray 20, lv'iedi 'ly of the intermediate portion 24 a burner opening 25 is formed and ar rangedto directthe burning fuel downwardly toward'the tray 20.

In operation, it is first necessary to place inthe recess 21 of the'grid 20 a small quantity of hydrocarbon oil. This oil is ignited and serves to heat the walls of the vapor izi'ngchamber so that as the oil is supplied to the chamber from the pipe 17 it is vapor- I ized and thus converted into a gas. This gas rises from the chamber 16 and flows into the ends of the burner pipe 24 and is finally discharged from the pipe through the burner opening 25, where it is ignited. The flames emanating from the burner opening are directed downwardly into contact with the tray 20, the latter serving to deflect the flames and heat upwardly into contact with the intermediate portion of the burner pipe 24:. By virtue of the fact that the flames are directed into contact with the tray 20, a heating of the walls of the vaporizing chamber 15 is effected, and the flames being directed upwardly also effects a heating of the burner pipe 24. In this manner it will be clear that the oil admitted to the vaporizing chamber is partly vaporized therein and the complete vaporization of the oil takes place while traversing the burner pipe 24, with the result of a perfect combustion of the fuel when ignited at the burner opening. In practice, it has been found that the vaporization or gasification of the fuel is such as to prevent formation or accumulation of carbon within the vaporizing chamber or the burner pipe 24 and that the burning fuel does not generate smoke.

As previously described, the ends 23 of the pipe 24 are reversely threaded to engage within the openings 22. By means of top thereof.

ber is relatively deep and that the pipe 17 enters thereinto at the extreme bottom thereof. It will be further observed that the respective branches of the burner pipe 24 enter the chamber almost at the extreme It will next be observed that the grid 20 has its side portions extended for a considerable distance over the re spective ends of said pipe 2a. It is accordingly manifest incident to these structural features of the invention that should the vaporizing chamber be flooded with oil, the film of oil at the lever of the body contained in the chamber will directly underlie the top wall of said chamber so as to be presented to the effective action of radiant heat passing from the top wall of the chamber and that in order to prevent the liquid from passing directly into the respective branches of the burner pipe 24 before it is perfectly vaporized, the sides of the grid which overlie said ends of the burner pipe, act to send radiant heat toward said ends with such maximum efliciency that proper vaporization is effected.

Although I have shown herein and have described only one form of oil burner embodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claim.

What I claim is:

A burner comprising a body having a relatively deep vaporizing chamber provided with a fuel inlet at itsbottom, a C- shapcd burner pipe having its respective ends connected with the chamber approximately at the top thereof, and a rectan gular tray formed as an intergral part of the body and having portions immediately overlying the ends of the burner pipe and extending over an appreciable length thereof the connecting portion of the pipe between said ends overlying the tray and having a burner orifice, the said deep chamber functioning to permit oil to rise therein so that a top film of oil is exposed directly to the action of radiant heat from the under side of the tray medially thereof, and the said sides of the tray serving to cause heat therefrom to radiate downward against the ends of said burner pipe for coaction with the under side of said tray so as to vaporize the fuel before it passes to the burner orlfice.

OLUF ANDERSEN.
